They have just started out a new store at Galleria and already I can see myself going there a lot. The owners are very nice people, very engaging and most important really want to service you and not just pinch your money.
If there is a book you don't see out there, you can always ask them to order it and you get it in 24 hours. They have moved to Galleria, DLF Phase 4. I haven't seen this one listed but I'm sure it's just as good !
